PEPE CUTTER AND WRENCH.

SPECIFICATION forming part of Letters Patent No. 232,937, dated October5, 1880.

Application filed August 21, 1880. (No model.)

To all whom it may concern:

Be it known that I, GENRY A. CHAPMAN, of Strawberry Point, in the countyof Clayton and State of Iowa, have invented a new and Improved PipeOntter and 'Wrench, of which the following. is a specification.

The object of this invention is to provide a simple, strong, andeffective tool that serves as a cutter and wrench for pipe and as anordinary monkey-wrench.

The invention consists of a tool having a movable reversible jaw whoselower end rests against an adjustable nut, which traverses on thescrewthreaded handle of the tool, and whose upper or operating end isheld to the shank of the fixed jaw by a clamp or yoke, and is adjustabletherein by a set-screw in said clamp or yoke.

Figure 1 is a perspective view of the device operating as pipe wrench ortongs. Fig. 2 is alongitudiual front elevation of the same. Fig. 3 is areduced side elevation ofthe device operating as a pipecutter. Fi g. 4is a reduced side elevation of the device operating as a monkey wrench.

Similar letters of reference indicate corresponding parts.

In the drawings, A represents the fixed shank of the tool, having at oneend the fixed o jaw a, while at the opposite end said shank A isprolonged into a screw-threaded handle, I),

- on which a nut, B, traverses, and to which a wooden handle may besecured.

O is a clamp or yoke attached to the sides of the shank A and extendedin front of and at right angles to it, and provided with a setscrew, D,that passes down through its crown.

E is the movable shank or jaw of the device, which consists of astraight bar having one end cut away at opposite corners, as shown at c0, thereby leaving a central projecting triangular point, d, that servesas a cutter or blade for cutting pipe.

When the tool is not in use the jaw or shank E is laid along the face ofthe shank A, within the yoke C, with its jaw end against the fixed jaw aand the nut B screwed up against its opposite end, and the set-screw Dis turned down upon it to hold it more securely. The nut B, instead ofsimply bearing against the end of said jaw E, may be suitably attachedthereto.

When the said tool is used as a pipe wrench or tongs, as shown in .Fig.1, the nut B is retracted on the handle I) of the device, the setscrew Dis turned up, and the jaw end of the jaw or shank E raised so as toadmit the pipe to be operated upon between the jaws to and E, which pipeis represented at 1 the fiat face f of said jaw E being made to engageupon the said pipe F by means of the screwing up of the nut B and thescrewing down of the set-screw D.

When the tool is used as a pipe-cutter the jaw E is reversed and thecuttingpoint (:5 brought in proper contact with the pipe E that is to becut by turning the nut B and set-screw D, as may be required.

The said tool may be used as an ordinary monkey-wrench by retracting thenut B so that the jaw E may be drawn back far enough along the face ofthe shank A to permit the jaws of the tool to embrace the nut g, orother object to be operated upon, when, by turning up the nut B, theobject 9 is held fast and the jaw E held firmly in place by turning downthe screw-nut D.

Having thus described my invention, what I claim as new, and desire tosecure by Let.- ters Patent, is-

As an improved article of manufacture, a pipe cutter and wrenchconstructed substantially as herein shown and described, consisting ofthe shank A, having jaw 60, screw-threaded handle I), carryingadjusting-nut B, yoke O, set-screw D, and adjustable reversiblecuttingjaw E, as set forth.
